If you stick that thumb in the ejection port and drop the slide a couple of times, it will shorten it so you won't have that problem. :eek: Seriously though, the Kahr has a small grip and if you have large hands, it is easy to bump the release. Try curling your thumb down like when you make a fist and that should eliminate the problem. Some people that shoot with their thumb straight actually hit the end of their thumb with the tip of their trigger finger, interfering with getting a shot off. 44 Man
